ABSTRACT

A method for treating objects with at least one treatment agent in a household device includes the step of operating a first part of an identification system to identify data of a second part of the identification system, the data of the second part of the identification system comprising information on a dosing device operable to dose the treatment agent, and the data of the second part of the identification system being associated with a packaging for the dosing device. The method also includes the further step of adapting a treatment of objects by the household device or a dosing of the treatment agent based upon the identified data.

The invention relates to a method and an arrangement for treating objects with at least one treatment agent in a household device, a household device for treating objects with at least one treatment agent, a packaging of at least one treatment agent and a dosing device for, dosing at least one treatment agent.

Various household devices for treating objects are known, such as, for example, washing machines for cleaning laundry and dishwashers for cleaning crockery, which use a plurality of cleaning agents which can be composed of various ingredients having different active parameters. That is, some of these ingredients require certain ambient conditions so that they can release their effect. Some of these ingredients cease to be effective under certain ambient conditions, such as enzymes, for example, at an ambient temperature higher than 50 degrees centigrade.

WO 01/07703 A1 discloses a device for the take up and dosed release of at least one active compound mixture in a washing machine, a dryer or a dish washer, comprising chambers for the take up of a dose of at least one active compound mixture respectively. The device also comprises an opening arrangement for the chambers, which is activated by means which in turn are activated by the conditions prevailing in the inside of the machine, which conditions prevail solely in the course of a washing, drying or dish-washing cycle.

WO 01/07704 describes a device for receiving and dispensing an active composition in a dosed manner into a washing machine, linen drier or a dishwasher, which comprises a storage chamber which receives at least double the amount of an individual dose of said active composition. This device also comprise a dosing chamber which is connected to the storage chamber by a passage in order to receive an individual dose of an active composition. A discharging passage is provided to discharge said active composition into the interior of the machine which, like the passage between the storage chamber and dosing chamber, is actuated by means which are activated by conditions inside the machine, existing exclusively during a wash, dry or dishwashing cycle.

The disadvantage of the devices described in WO 01/07703 A1 and in WO 01/07704 A1 is that the dispensing of the dose into the interior of the machine can be activated by ambient conditions, i.e. dosing parameters and/or that after the dispensing, ambient conditions may be present which are disadvantageous for the efficiency of the active composition or individual ingredients thereof or which hinder the efficiency of the active composition of individual ingredients thereof.

EP 1 088 927 A1 discloses a device for dosing and/or dispensing at least one product into an appliance for treating laundry or dishes, said device comprising at least one sensor for determining the ambient conditions. This device contains a teachable device which can identify up to three treatment programmes after a few learning runs. If one of the learned treatment programmes is executed by the device after the learning runs, the product is dispensed into the interior of the appliance at a time determined by the device.

The disadvantage of the devices described in EP 1 088 927 A1 is that the device requires a few learning runs of a treatment programme before the time at which the product is dispensed can be adapted to this treatment programme. In addition, in this device also the ambient conditions at and/or after the time at which the product is dispensed into the interior of the appliance can be disadvantageous for the efficiency of the product or of some of its ingredients.

It is the object of the invention to improve the efficiency of treatment of objects in a household device.

This object is solved in an arrangement according to the invention of the type specified initially in that the arrangement comprises a household device for treating objects with at least one treatment agent, that the arrangement comprises a packaging for the at least one treatment agent and/or a dosing device for dosing the at least one treatment agent, that the household device comprises a first part of an identification system which makes it possible to identify data of a second part of said identification system, which comprises information on at least one treatment agent and/or on the dosing device, that the packaging and/or the dosing device comprises the second part of said identification system, and that the treatment and/or the dosing is automatically adapted to this information.

In addition, a household device of the type specified initially according to the invention is also provided to solve the object, wherein the household device comprises a first part of an identification system which is configured such that it can identify data of a second part of the identification system, which comprises information on the at least one treatment agent and/or on the dosing device for dosing the at least one treatment agent, and that the treatment and/or the dosing is automatically adapted to this information.

In addition, a packaging of the type specified initially according to the invention is provided to solve the object, said packaging being configured such that the packaging comprises a second part of an identification system which is configured such that its data can be identified by a first part of the identification system and that the data comprises information on a composition and/or active parameters of the at least one treatment agent.

Furthermore, a dosing device of the type specified initially according to the invention is provided to solve the object, said dosing device being configured such that it can be inserted into a household device for treating objects, the dosing device comprises the second part of the identification system which is configured such that its data can be identified by the first part of the identification system and that the data comprises information on the dosing device.

Finally, the object is solved in a method of the type specified initially according to the invention wherein the household device comprises a first part of an identification system which identifies data of a second part of the identification system, which comprises information on the at least one treatment agent and/or on a dosing device for dosing the at least one treatment agent, wherein a packaging for the at least one treatment agent and/or the dosing device comprises a second part of the identification system, and that the treatment and/or the dosing is automatically adapted to this information.

Since the treatment of objects in the household appliance can be adapted to information on the treatment agent used and/or to information on the dosing device used, the efficiency of the treatment is largely ensured in a simple fashion. In particular, the treatment is adapted to information on the treatment agent so that the ambient conditions in the household device during the treatment are optimal for the efficiency of the treatment agent. For this purpose it is especially advantageous if the information on the treatment agent used comprises the composition and/or the active parameters of the treatment agent.

In addition, the treatment can be adapted to information on the dosing device so that the dosing of the treatment agent can be controlled with the aid of the ambient conditions in the household device during the treatment so that the treatment is efficiently efficacious. The information on the treatment agent and/or on the dosing device can be supplied to the household device using the identification system.

If the identification system comprises especially a contact-free identification system, an advantageous further development consists in the fact that the household device with the first part of the identification system comprises a reader for transponder chips and that the packaging of the at least one treatment agent and/or the dosing device for dosing the at least one treatment agent with the second part of the identification system comprises a transponder chip.

In this way it is particularly easy to supply information from the packaging and/or from the dosing device into the household device since the data from the transponder chip can be read by the reader from a distance of about one metre.

According to an advantageous embodiment of the invention, the household device comprises a dishwasher or a washing machine. Especially for use in dishwashers or in washing machines there are a plurality of treatment agents having a wide range of compositions which require different ambient conditions for optimal efficiency. In this case, adapting the treatment to the composition of the treatment agent used quite particularly improves the efficiency of the treatment agent and thus the efficiency of the treatment.
